When it comes to weight reduction, the list of usual suspects includes wheels, seats, door cards, windows, body panels, bumpers, batteries and the rest. But what about the starter motor? Would you believe the standard Bosch starter motor in most aircooled 911s weighs in at a hefty 11kg? Stuttgart Classica’s lightweight alternative tips the scales at just 3.8kg, making for a worthwhile saving. Compatible with all 911s up to 1989, this motor is stronger and more powerful than the OE starter with a 2kw output, plus a gear reduction design for maximum torque when starting high compression engines. The steel reduction gears also make the starter more reliable than many other starters on the market. Priced at £225, shipping is free to the UK and £60 for worldwide orders from stuttgart-classica.co.uk.
